Nat Gas Inventories Build Early in US

By: Tom Pawlicki, Senior Specialist, Market Intelligence

The natural gas market has seen more bullish news from the Middle East in the last few days, however, Henry Hub prices remain subdued based on high US inventories and an inability to export any more LNG.

QatarEnergy said on March 4 that it would declare force majeure on gas exports due to the risk to its production facilities and the closure of the Strait of Hormuz by Iran. It said that once it eventually makes a decision to restart, it would take another two weeks to get equipment up to speed. That was upended on Wednesday when Iran attacked the facility. After evaluating the damage, Qatari officials said today that the attack damaged 17% of its output capacity and that it would take 3-5 years to restore that capacity.

The Iranian attack on Qatar was revenge for the Israeli attack on Iran’s South Pars gas field earlier in the week. President Trump tried to defuse the issue of energy infrastructure attacks today by saying that no more Iranian energy would be attacked, but if Iran attacks Qatar again, the US would completely destroy South Pars. Iran may have agreed, as Iranian Foreign Minister Abbas Araghchi said that Iran would have “zero restraint” if the country’s infrastructure is hit again. It will remain to be seen whether Iran holds off on more energy infrastructure attacks, but the “if-then” statement from Iran may give some hope. Oil prices were able to fall from their late-morning highs throughout the second half of the trading day.

Natural gas prices in the US remain subdued in the low $3.00/MMBtu area despite the events in the Middle East, while LNG prices in Europe have soared. LNG prices in Europe jumped from around €32/MWh before the war to around €55/MWh last week. The news regarding QatarEnergy pushed prices above €60/MWh today.

US prices remain weighed down by an inability to export more and by high inventory levels. US waterborne LNG exports rose to a high of 16.68 Bcf/d in December, and were last reported at 16.07 Bcf/d in February. Capacity is somewhere in the 17-19 Bcf/d range, which would imply that exporters are running somewhere in the 90%-100% of capacity range and are likely near maximum levels.

Natural gas inventories in today’s update from the EIA showed a build of 35 Bcf. If the prior week represents the low point for the seasonal cycle and there are no more withdrawals, it would mark one of the earliest builds in inventories since 2010. The bottom made in the week ending March 6 edged out the low point in 2025 in the week ending March 7 and the bottom in 2012 made in the week ending March 9. Since 2010, the weekly low has been made on average around March 24. The five-year average reaches its low point this year in the week ending March 27.

Natural gas inventory levels are healthy too, with 1,848 Bcf at this year’s low point holding above the 15-year average of low points at 1,708 Bcf. The US market remains flush with gas, which is interesting given the doubling in prices that took place in late-January on cold weather that was completely expected.

The outlook going forward seems to show global prices focusing on potential support from the continuation of the war in the Middle East, while the bearish side looks at US prices being weighed by the inability to export more LNG and because of the approaching shoulder season of weak demand for gas.
